Kikusui TOS3200 - Status Register and Status Report Function

150 TOS3200
Status Register and Status Report Function
IEEE488.2 and SCPI registers are used for the status reports.
In each SCPI status register, there are sub registers, CONDition register, EVENt register,
ENABle register, PTRansition filter, and NTRansition filter.
Fig. 8-4 shows the SCPI status register structure. The character “+” represents the the logical
OR of the register bits.
CONDition register
The CONDition register transits automatically and reflects the condition of the TOS3200 in
real-time. Reading this register does not affect the contents.
EVENt register
The EVENt register bits are automatically set according to the changes in the CONDition reg-
ister. The rule varies depending on the positive and negative transition filters (PTRansition
and NTRansition). The EVENt register is reset when it is read.
ENABle register
The ENABle register enables the reports to the summary bit or status bit of the event bit.
Transition filter
Use the PTRansition (positive transition) filter to report events when the condition changes
from false to true.
Use the NTRansition (negative transition) filter to report events when the condition changes
from true to false.
If both the positive filter and the negative filter are set to true, events can be reported each
time the status changes.
If both filters are cleared, event reporting will be disabled.
